FIG. 1 is a schematic perspective view illustrating the lens movingapparatus 100 according to an embodiment, and FIG. 2 is an explodedperspective view of the lens moving apparatus 100 illustrated in FIG. 1.

Referring to FIGS. 1 and 2, the lens moving apparatus 100 may include acover member 300, an upper elastic member 150, a sensor board 180, afirst position sensor 170, a first coil 120, a bobbin 110, a housing140, a magnet 130, a lower elastic member 160, a plurality of supportmembers 220, a second coil 230, a circuit board 250, a second positionsensor 240, and a base 210.

First, the cover member 300 will be described.

The cover member 300 defines an accommodation space along with the base210, such that the upper elastic member 150, the bobbin 110, the firstcoil 120, the housing 140, the magnet 130, the lower elastic member 160,the support members 220, the second coil 230, and the circuit board 250are accommodated in the accommodation space.

The cover member 300 may take the form of a box, which has an openbottom and includes an upper end portion and sidewalls. The bottom ofthe cover member 300 may be coupled to the top of the base 210. Theupper end portion of the cover member 300 may have a polygonal shapesuch as, for example, a square or octagonal shape.

The cover member 300 may have a bore formed in the upper end portionthereof in order to expose a lens (not illustrated) coupled to thebobbin 110 to outside light. In addition, the bore of the cover member300 may be provided with a window formed of a light-transmittingmaterial, in order to prevent impurities, such as, for example, dust ormoisture, from entering a camera module.

Although the material of the cover member 300 may be a non-magneticmaterial such as, for example, SUS in order to prevent the cover member300 from being attracted by the magnet 130, the cover member 300 may beformed of a magnetic material and may function as a yoke.

FIG. 3 is an assembled perspective view illustrating the lens movingapparatus 100 after removal of the cover member 300 of FIG. 1, and FIG.4 is an exploded perspective view of the bobbin 110, the first coil 120,the magnet 130, the first position sensor 170, and the sensor board 180illustrated in FIG. 2.

Next, the bobbin 110 will be described.

Referring to FIGS. 3 and 4, the bobbin 110 is placed inside the housing140, which will be described below, and is movable in the firstdirection, for example, in the Z-axis via electromagnetic interactionbetween the first coil 120 and the magnet 130.

Although not illustrated, the bobbin 110 may include a lens barrel (notillustrated) in which at least one lens is installed. The lens barrelmay be coupled inside the bobbin 110 in various manners.

For example, the bobbin 110 may be configured to have a bore for themounting of the lens or the lens barrel. The bore may have a circular,elliptical, or polygonal shape, without being limited thereto.

The bobbin 110 may include first and second protrusions 111 and 112.

The first protrusion 111 of the bobbin 110 may include a guide portion111 a and a first stopper 111 b.

The guide portion 111 a of the bobbin 110 may serve to guide aninstallation position of the upper elastic member 150. For example, asexemplarily illustrated in FIG. 3, the guide portion 111 a of the bobbin110 may guide a first frame connection portion 153 of the upper elasticmember 150.

The second protrusion 112 of the bobbin 110 may be formed on an outercircumferential surface 110 b of the bobbin 110 so as to protrude in thesecond and third directions, which are perpendicular to the firstdirection. In addition, the second protrusion 112 of the bobbin 110 maybe provided on an upper surface 112 a thereof with a first coupling boss113 a, which is coupled to a first inner frame 151 of the upper elasticmember 150, which will be described below.

The first stopper 111 b of the first protrusion 111 and the secondprotrusion 112 of the bobbin 110 may serve to prevent the bottom surfaceof the body of the bobbin 110 from directly colliding with the base 210and the upper surface of the circuit board 250 even if the bobbin 110moves beyond a prescribed range due to, for example, external shock whenbeing moved in the optical axis direction or in the first direction,which is parallel to the optical axis, for auto-focusing.

To this end, the first stopper 111 b of the bobbin 110 may far protrudein the second or third direction, which is the circumferentialdirection, from the outer circumferential surface 110 b of the bobbin110 than the guide portion 111 a of the bobbin 110. In addition, thesecond protrusion 112 of the bobbin 110 may far protrude laterally thanthe upper surface 112 a on which the upper elastic member 150 is seated.

The bobbin 110 may have a support groove 114 provided between an innercircumferential surface 110 a and the outer circumferential surface 110b of the bobbin 110 so as to allow the sensor board 180 to be insertedinto the bobbin 110 in the first direction. For example, the supportgroove 114 of the bobbin 110 may be provided between the innercircumferential surface 110 a of the bobbin 110 and the first and secondprotrusions 111 and 112 so as to enable the insertion of the sensorboard 180.

The bobbin 110 may have a receiving recess 116, which is suitable toreceive the first position sensor 170 disposed, coupled, or mounted onthe sensor board 180.

For example, the receiving recess 116 of the bobbin 110 may be providedin the space between the first and second protrusions 111 and 112 of thebobbin 110, so as to allow the first position sensor 170 mounted on thesensor board 180 to be inserted in the first direction.

The bobbin 110 may have a second coupling boss 117 (see FIG. 9) formedon the lower surface thereof so as to be coupled and fixed to the lowerelastic member 160.

When the position at which the lower surfaces of the first and secondprotrusions 111 and 112 of the bobbin 110 come into contact with abottom surface 146 a of a first seating groove 146 of the housing 140 isset to an initial position, auto-focusing may be controlled so as to beperformed in a single direction. That is, auto-focusing may beimplemented such that the bobbin 110 moves upward when current issupplied to the first coil 120, and moves downward when the supply ofcurrent is interrupted.

However, when the position at which the lower surfaces of the first andsecond protrusions 111 and 112 of the bobbin 110 are spaced apart fromthe bottom surface 146 a of the first seating groove 146 by a givendistance is set to an initial position, auto-focusing may be controlledso as to be performed in two directions. For example, auto-focusing maybe implemented such that the bobbin 110 moves upward when forwardcurrent is applied to the first coil 120 and moves downward when reversecurrent is applied to the first coil 120.

Next, the first coil 120 will be described.

The first coil 120 is disposed on the outer circumferential surface 110b of the bobbin 110.

The first coil 120 may be located so as not to overlap the firstposition sensor 170 in the direction perpendicular to the optical axis,for example, in the X-axis or the Y-axis.

For example, in order to ensure that the first coil 120 and the firstposition sensor 170 do not interfere or overlap each other in thedirection perpendicular to the optical axis, the first position sensor170 may be located on the upper portion of the outer circumferentialsurface 110 b of the bobbin 110, and the first coil 120 may be locatedon the lower portion of the outer circumferential surface 110 b of thebobbin 110.

The first coil 120, as exemplarily illustrated in FIG. 4, may be woundso as to surround the outer circumferential surface 110 b of the bobbin110 in the direction in which the first coil 120 rotates about theoptical axis. For example, the first coil 120 may be inserted into andcoupled to a coil groove formed in the outer circumferential surface 110b of the bobbin 110, without being limited thereto.

As exemplarily illustrated in FIG. 4, the first coil 120 may be directlywound around the outer circumferential surface 110 b of the bobbin 110.In another embodiment, the first coil 120 may take the form of an angledring-shaped coil block, without being limited thereto.

The first coil 120 may produce electromagnetic force via interactionwith the magnet 130 when current is supplied thereto, thereby moving thebobbin 110 in the first direction using the electromagnetic force. Thefirst coil 120 may be disposed so as to correspond to or face the magnet130.

Next, the first position sensor 170 and the sensor board 180 will bedescribed.

The first position sensor 170 may be disposed, coupled, or mounted onthe bobbin 110, so as to move along with the bobbin 110. The firstposition sensor 170 may move along with the bobbin 110 when the bobbin110 moves in the first direction.

The first position sensor 170 may sense the strength of a magnetic fieldof the magnet 130 depending on the movement of the bobbin 110, and mayoutput a signal based on the sensed result.

The first position sensor 170 may be electrically connected to thesensor board 180. The first position sensor 170 may take the form of adriver including a Hall sensor, or may take the form of a positiondetection sensor alone such as, for example, a Hall sensor.

The first position sensor 170 may be disposed, coupled, or mounted onthe bobbin 110 in various forms, and may receive current in various waysdepending on the form in which the first position sensor 170 isdisposed, coupled, or mounted.

The first position sensor 170 may be disposed, coupled, or mounted onthe outer circumferential surface 110 b of the bobbin 110. For example,the first position sensor 170 may be disposed, coupled, or mounted onthe sensor board 180, and the sensor board 180 may be coupled to thebobbin 110.

The first position sensor 170 may be electrically connected to at leastone of the upper elastic member 150 and the lower elastic member 160.For example, the first position sensor 170 may be electrically connectedto the upper elastic member 150.

The sensor board 180 may be mounted on the bobbin 110, and may movealong with the bobbin 110 in the optical axis direction or in thedirection parallel to the optical axis. For example, the sensor board180 may be inserted into the support groove 114 of the bobbin 110 andcoupled to the bobbin 110. The sensor board 180 is sufficient so long asit is mounted on the bobbin 110, and FIG. 4 illustrates the sensor board180 having a ring shape, without being limited thereto.

The first position sensor 170 may be attached to and supported by thefront surface of the sensor board 180 using an adhesive member such as,for example, a double-sided tape, or epoxy.

The outer circumferential surface 110 b of the bobbin 110 may becomprised of first side surfaces 110 b-1 and second side surfaces 110b-2. The first side surfaces 110 b-1 correspond to first side portions141 of the housing 140 on which the magnet 130 is disposed. The secondside surfaces 110 b-2 are located between the first side surfaces 110b-1 so as to connect the first side surfaces 110 b-1 to one another.

The first position sensor 170 may be disposed on any one of the firstside surfaces 110 b-1 of the bobbin 110. For example, the receivingrecess 116 of the bobbin 110 may be provided at any one of the firstside surfaces 110 b-1 of the bobbin 110, and the first position sensor170 may be located in the receiving recess 116 of the bobbin 110.

The first position sensor 170 may be disposed, coupled, or mounted on anupper portion A1, a middle portion A2, or a lower portion A3 of theouter circumferential surface of the sensor board 180 in various forms.At this time, the first position sensor 170 may receive current from theoutside through a circuit of the sensor board 180.

The sensor board 180 may include a body 182, elastic member contactportions 184-1 to 184-4, and a circuit pattern.

The body 182 of the sensor board 180 may include a first segment 182 aon which the first position sensor 170 is disposed, coupled, or mounted,and a second segment 182 b connected to the first segment 182 b andconfigured so as to be inserted into the support groove 114 of thebobbin 110. The elastic member contact portions 184-1 to 184-4 may beprovided on the second segment 182 b.

For example, in order to allow the sensor board 180 to be easilyinserted into the support groove 114 of the bobbin 110, the secondsegment 182 b of the sensor board 180 may be provided with an opening181.

The elastic member contact portions 184-1 to 184-4 of the sensor board180 may be connected to the first inner frame 151 of the upper elasticmember 150.

The circuit pattern of the sensor board 180 may be formed on the body182 of the sensor board 180, and may electrically connect the firstposition sensor 170 and the elastic member contact portions 184-1 to184-4 to each other.

For example, in order to increase the distance between the firstposition sensor 170 and the first coil 120, the first position sensor170 may be disposed, coupled, or mounted on the upper portion of theouter circumferential surface of the sensor board 180. This serves toprevent the malfunction and errors of the first position sensor 170 bypreventing the first position sensor 170 from being affected by themagnetic field of the first coil 120 within a high frequency range.

At least a portion of the first position sensor 170 may overlap themagnet 130 in the direction perpendicular to the optical axis, withoutbeing limited thereto.

A lens moving apparatus in accordance with another embodiment mayfurther include a separate sensing magnet for the first position sensor170. The separate sensing magnet may be mounted on the bobbin 110 or thehousing 140. At this time, at least a portion of the first positionsensor 170 may overlap the sensing magnet in the direction perpendicularto the optical axis, rather than overlapping the magnet 130.

Next, the housing 140 will be described.

The housing 140 may support the magnet 130, and may accommodate thebobbin 110 therein so as to allow the bobbin 110 to move in the firstdirection, which is parallel to the optical axis.

The housing 140 may generally have a hollow column shape. For example,the housing 140 may have a polygonal (e.g., a square or octagonal) orcircular bore.

FIG. 5 is a perspective view of the housing 140 illustrated in FIG. 2,FIG. 6 is a bottom perspective view of the housing 140 illustrated inFIG. 2, FIG. 7 is a sectional view taken along line I-I′ of FIG. 3, FIG.8 is a perspective view illustrating the coupled state of the bobbin110, the housing 140, the upper elastic member 150, the first positionsensor 170, the sensor board 180, and the support members 220illustrated in FIG. 2, and FIG. 9 is a bottom perspective viewillustrating the coupled state of the bobbin 110, the housing 140, thelower elastic member 160, and the support members 220 illustrated inFIG. 2.

The housing 140 may have the first seating groove 146 formed at aposition thereof corresponding to the first and second protrusions 111and 112 of the bobbin 110.

The housing 140 may have a third protrusion 148, which corresponds toeach of the second side surfaces 110 b-2 of the bobbin 110. The thirdprotrusion 148 of the housing 140 may prevent the bobbin 110 from beingrotated even if the bobbin 110 receives force in the direction in whichthe bobbin 110 is rotated about the optical axis, rather than beingrotated in the optical axis direction.

For example, the upper edge of the outer periphery of the housing 140may have a square plan shape, whereas the lower edge of the innerperiphery may have an octagonal plan shape, as exemplarily illustratedin FIGS. 5 and 6. The housing 140 may include a plurality of sideportions. For example, the housing 140 may include four first sideportions 141 and four second side portions 142.

The magnet 130 may be mounted on the first side portions 141 of thehousing 140. The second side portions 142 of the housing 140 may belocated respectively between the two neighboring first side portions141. The support members 220 may be disposed on the second side portions142 of the housing 140. The first side portions 141 of the housing 140may interconnect the second side portions 142 of the housing 140.

The housing 140 may have magnet seats 141 a provided on inner surfacesof the first side portions 141 in order to accommodate magnets 130-1 to130-4. Each of the magnets 130-1 to 130-4 may be fixed to the magnetseat 141 a, which is provided on a corresponding one of the first sideportions 141 of the housing 140.

The magnet seat 141 a of the housing 140 may be configured as a groovehaving a size corresponding to the size of the magnet 130. An aperturemay be formed in the bottom surface of the magnet seat 141 a of thehousing 140. The lower surface of the magnet 130 fixed to the magnetseat 141 a may face the second coil 230.

The magnet 130 may be secured to the magnet seat 141 a of the housing140 using an adhesive, without being limited thereto, and for example,an adhesive member such as a double-sided tape may be used.

Alternatively, the magnet seat 141 a of the housing 140 may beconfigured as a mounting hole, which allows a portion of the magnet 130to be fitted thereinto or to be exposed therefrom, rather than beingconfigured as the groove illustrated in FIG. 6.

The first side portion 141 of the housing 140 may be oriented parallelto the side surface of the cover member 300. In addition, the first sideportion 141 of the housing 140 may be larger than the second sideportion 142. The second side portion 142 of the housing 140 may beprovided with first through-holes 147 a and 147 b, through which thesupport members 220 pass.

In addition, in order to prevent the housing 140 from directly collidingwith the inner side surface of the cover member 300 illustrated in FIG.1, the housing 140 may be provided at the upper end thereof with asecond stopper 144.

The housing 140 may have at least one first upper support boss 143formed on the upper surface thereof for the coupling of the upperelastic member 150.

For example, the first upper support boss 143 of the housing 140 may beformed on the upper surface of the housing 140 corresponding to thesecond side portion 142 of the housing 140. The first upper support boss143 of the housing 140 may have a semispherical shape, cylindrical shapeor prism shape, without being limited thereto.

The housing 140 may have second a lower support boss 145 formed on thelower surface thereof for the coupling and fixing of the lower elasticmember 160.

In order to define paths for the passage of the support members 220 andto ensure the space to be filled with silicon, which serves as a damper,the housing 140 may have a first recess 142 a formed in the second sideportion 142.

The housing 140 may have a plurality of third stoppers 149 protrudingfrom the side surface thereof. The third stoppers 149 serve to preventthe housing 140 from colliding with the cover member 300 when thehousing 140 moves in the second and third directions.

In order to prevent the lower surface of the housing 140 from collidingwith the base 210 and/or the circuit board 250 which will be describedbelow, the housing 140 may further have a fourth stopper (notillustrated) protruding from the lower surface thereof. Through thisconfiguration, the housing 140 may be downwardly spaced apart from thebase 210 and may be upwardly spaced apart from the cover member 300. Inthis way, the housing 140 may perform hand tremor compensation in thedirection perpendicular to the optical axis.

The magnet 130 may be accommodated inside the first side portion 141 ofthe housing 140, without being limited thereto. In another embodiment,the magnet 130 may be disposed outside the first side portion 141 of thehousing 140, or may be disposed inside or outside the second sideportion 142 of the housing 140.

Next, the magnet 130 will be described.

Each of the magnets 130-1 to 130-4 may be configured as a single body,and may be a unipolar magnet, the inner side and the outer side of whichhave different polarities.

For example, the magnets 130-1 to 130-4 may be disposed such that theboundary between an S-pole and an N-pole of each magnet is parallel tothe direction perpendicular to the direction in which the magnet 130 andthe first coil 120 face each other.

For example, although each of the magnets 130-1 to 130-4 may be orientedsuch that the surface thereof facing the first coil 120 is the S-pole132 and the opposite surface is the N-pole 134, the embodiment is notlimited thereto, and the opposite configuration is also possible.

At least two or more magnets 130 may be installed, and in theembodiment, four magnets 130 may be installed. The shape of the magnet130 may correspond to the shape of the first side portion 141 of thehousing 140, without being limited thereto. For example, the magnet 130may have a rectangular shape, without being limited thereto, and themagnet 130 may have a triangular or diamond shape based on the positionthereof on the housing 140.

Although the surface of the magnet 130 facing the first coil 120 may beflat, the embodiment is not limited thereto. The surface of the magnet130 facing the first coil 120 may be curved.

One pair of magnets 130-2 and 130-4 among the magnets 130-1 to 130-4 maybe arranged parallel to each other in the second direction (in theX-axis), and the other pair of magnets 130-1 and 130-3 may be arrangedparallel to each other in the third direction (in the Y-axis).

In another embodiment, the magnet 130 may be a bipolar magnet. At thistime, the kinds of bipolar magnets may be broadly divided into ferrite,alnico, and rare-earth magnets, for example, and may be sorted into aP-type and an F-type according to the form of a magnetic circuit. Theembodiment is not limited as to the kinds of bipolar magnets.

Next, the upper elastic member 150, the lower elastic member 160, andthe support members 220 will be described.

The upper elastic member 150 and the lower elastic member 160elastically support the bobbin 110. The support members 220 may supportthe housing 140 so as to be movable relative to the base 210 in thedirection perpendicular to the optical axis, and may electricallyconnect at least one of the upper and lower elastic members 150 and 160to the circuit board 250.

FIG. 11 is an assembled perspective view illustrating the upper elasticmember 150, the lower elastic member 160, the first position sensor 170,the sensor board 180, the base 210, the support members 220, and thecircuit board 250 illustrated in FIG. 2.

The upper elastic member 150 may include a plurality of upper elasticmembers 150-1 to 150-4 (and 150-5 and 150-6), which are electricallyseparated from one another.

For example, the separate upper elastic members 150-1 to 150-4 (and150-5 and 150-6) may be point symmetrical to one another in the X-Yplane on the basis of the center of the bobbin 110. Here, “pointsymmetry” refers to symmetry in which two forms overlap each other whenthe two forms are rotated by 180 degrees about a single rotation centerpoint.

The elastic member contact portions 184-1 to 184-4 of the sensor board180 may be electrically connected to at least one of the upper elasticmember 150 and the lower elastic member 160.

FIG. 11 illustrates that the elastic member contact portions 184-1 to184-4 of the sensor board 180 come into electrical contact with theupper elastic members 150-1 to 150-4, without being limited thereto. Inanother embodiment, the elastic member contact portions 184-1 to 184-4of the sensor board 180 may come into electrical contact with the lowerelastic member 160, or may come into electrical contact with both theupper elastic member 150 and the lower elastic member 160.

The respective elastic member contact portions 184-1 to 184-4 of thesensor board 180, which are electrically connected to the first positionsensor 170, may be electrically connected to a corresponding one of theupper elastic members 150-1 to 150-4. In addition, the respective upperelastic members 150-1 to 150-4 may be electrically connected to acorresponding one of the support members 220-1 to 220-4.

Each one 150 a of the first and third upper elastic members 150-1 and150-3 may include a first inner frame 151, a first-first outer frame 152a, and a first frame connection portion 153.

Each one 150 b of the second and fourth upper elastic members 150-2 and150-4 may include the first inner frame 151, a first-second outer frame152 b, and the first frame connection portion 153.

The first inner frame 151 of each of the upper elastic members 150-1 to150-4 may be coupled or fixed to the bobbin 110. For example, the firstcoupling boss 113 a of the bobbin 110 may be inserted into asecond-first through-hole 151 a formed in the first inner frame 151 ofeach of the upper elastic members 150-1 to 150-4, and then both thefirst coupling boss 113 a and the second-first through-hole 151 a may befixed to each other via thermal bonding, or using an adhesive such as,for example, epoxy. The first inner frame 151 of each of the upperelastic members 150-1 to 150-4 may be electrically connected to acorresponding one of the elastic member contact portions 184-1 to 184-4of the sensor board 180.

The first-first and first-second outer frames 152 a and 152 b of theupper elastic members 150-1 to 150-4 may be coupled to the housing 140and may be connected to the support members 220.

The first frame connection portion 153 of each of the upper elasticmembers 150-1 to 150-4 may connect the first inner frame 151 to thefirst-first outer frame 152 a or the first-second outer frame 152 b.Although the first-second outer frame 152 b may be formed by bisectingthe first-first outer frame 152 a, the embodiment is not limitedthereto. In another embodiment, the first-first outer frame 152 a may bebisected, and each part of the bisected first-first outer frame 152 amay have the same shape as or may be symmetrical to the first-secondouter frame 152 b.

The first frame connection portion 153 of each of the upper elasticmembers 150-1 to 150-4 may be bent at least one time so as to form agiven pattern. Upward and/or downward movement of the bobbin 110 in thefirst direction may be elastically supported via position variation andfine deformation of the first frame connection portion 153 of each ofthe upper elastic members 150-1 to 150-4.

The first-first or first-second outer frame 152 a or 152 b of the upperelastic member 150 illustrated in FIG. 11 may be coupled and fixed tothe first upper support boss 143 of the housing 140.

In the embodiment, each of the first-first and first-second outer frames152 a and 152 b may be formed with a second-second through-hole 157,which has a shape and position corresponding to those of the first uppersupport boss 143. At this time, the first upper support boss 143 and thesecond-second through-hole 157 may be fixed to each other via thermalbonding, or using an adhesive such as, for example, epoxy.

After the first inner frames 151 are coupled to the bobbin 110 and thefirst-first and first-second outer frames 152 a and 152 b are coupled tothe housing 140, conductive connections CP11, CP12, CP13 and CP14 areperformed on the elastic member contact portions 184-1 to 184-4 of thesensor board 180 and the first inner frames 151 using such as, forexample, solders or conductive epoxy, as illustrated in FIG. 8.

Through the conductive connections CP11, CP12, CP13 and CP14, (+) powerand (−) power may be applied to the first position sensor 170, and thefirst position sensor 170 may output a positive (+) output signal ornegative (−) output signal. In addition, in order to enable the firstposition sensor 170 to receive (+) power and (−) power from the circuitboard 250 and to output a positive (+) output signal or negative (−)output signal to the circuit board 250, the upper elastic member 150 maybe divided into the first to fourth upper elastic members 150-1 to150-4.

The respective first to fourth upper elastic members 150-1 to 150-4 maybe connected to the circuit board 250 via the support members 220-1 to220-4. That is, each of the first to fourth upper elastic members 150-1to 150-4 may be electrically connected to the circuit board 250 via atleast one of the support members 220-1 to 220-4.

For example, the first upper elastic member 150-1 may be electricallyconnected to the circuit board 250 via at least one of first-first andfirst-second support members 220-1 a and 220-1 b.

The second upper elastic member 150-2 may be electrically connected tothe circuit board 250 via a second support member 220-2. The third upperelastic member 150-3 may be electrically connected to the circuit board250 via at least one of third-first and third-second support members220-3 a and 220-3 b. The fourth upper elastic member 150-4 may beelectrically connected to the circuit board 250 via a fourth supportmember 220-4. In this way, the first position sensor 170 may receivepower supplied from the circuit board 250 through the support members220-1 to 220-4 and the first to fourth upper elastic members 150-1 to150-4, or may output signals to the circuit board 250.

The support members 220-1 to 220-4 may be connected to the circuit board250 through holes 230 a (see FIG. 10) formed in a circuit member 231,which will be described below. In another embodiment, no holes may beformed in the circuit member 231 and the circuit board 250, and thesupport members 220 may be electrically connected to the circuit member231 via, for example, soldering.

Meanwhile, the lower elastic member 160 may include first and secondlower elastic members 160-1 and 160-2, which are electrically separatedfrom each other.

The first coil 120 may be connected to the support members 220 throughthe first and second lower elastic members 160-1 and 160-2.

Each of the first and second lower elastic members 160-1 and 160-2 mayinclude at least one second inner frame 161-1 or 161-2, at least onesecond outer frame 162-1 or 162-2, and at least one second frameconnection portion 163-1 or 163-2.

The second inner frames 161-1 and 161-2 of the first and second lowerelastic members 160-1 and 160-2 may be coupled to the bobbin 110, andthe second outer frames 162-1 and 162-2 may be coupled to the housing140.

The second-first frame connection portion 163-1 of the first lowerelastic member 160-1 may connect the second inner frame 161-1 and thesecond outer frame 162-1 to each other, and the second-second frameconnection portion 163-2 of the second lower elastic member 160-2 mayconnect the second inner frame 161-2 and the second outer frame 162-2 toeach other.

Both ends of the first coil 120 may be electrically connected to thefirst and second lower elastic members 160-1 and 160-2. For example, oneend of the first coil 120 may be electrically connected to the secondinner frame 161-1 of the first lower elastic member 160-1, and the otherend of the first coil 120 may be electrically connected to the secondinner frame 161-2 of the second lower elastic member 160-2. The firstand second lower elastic members 160-1 and 160-2 may receive power ofdifferent polarities and may transmit the power to the first coil 120.In order to transmit the power of different polarities to the first coil120 as described above, the lower elastic member 160 may be bisectedinto the first and second lower elastic members 160-1 and 160-2.

At least of the second-first and second-second frame connection portions163-1 and 163-2 may be bent at least one time so as to form a givenpattern.

In addition, the upper elastic member 160 may further include fifth andsixth upper elastic members 150-5 and 150-6, which are electricallyseparated from the first to fourth elastic members 150-1 to 150-4. Thefifth and sixth upper elastic members 150-5 and 150-6 may be spacedapart from each other and may be electrically separated from each other.

Each of the fifth and sixth upper elastic members 150-5 and 150-6 may becoupled to the housing 140, and may be electrically connected to supportmembers 220-5 to 220-8.

The fifth and sixth upper elastic members 150-5 and 150-6 may be coupledto only the housing 140 without being coupled to the bobbin 110, and mayelastically support the housing 140. That is, the fifth and sixth upperelastic members 150-5 and 150-6 may be spaced apart from the bobbin 110and may not come into contact with the bobbin 110.

Some support members 220-6 and 220-8 among the support members 220-5 to220-8, which are coupled to the fifth and sixth upper elastic members150-5 and 150-6, may be connected to the second outer frames 162-1 and162-2 of the lower elastic members 160-1 and 160-2, and the remainingsupport members 220-5 and 220-7 among the support members 220-5 to 220-8may be electrically connected to the circuit board 250 through the holes230 a formed in the circuit member 231.

For example, the fifth upper elastic member 150-5 may be connected tothe fifth and sixth support members 220-5 and 220-6, and the sixth upperelastic member 150-6 may be connected to the seventh and eighth supportmembers 220-7 and 220-8.

Each of the fifth and sixth upper elastic members 150-5 and 150-6 mayhave through-holes for the coupling of the support members 220-5 to220-8, and a through-hole for the coupling of the first upper supportboss 143.

The first lower elastic member 160-1 may be electrically connected tothe circuit board 250 via the sixth support member 220-6, the fifthupper elastic member 150-5, and the fifth support member 220-5. Thesecond lower elastic member 160-2 may be electrically connected to thecircuit board 250 via the eighth support member 220-8, the sixth upperelastic member 150-6, and the seventh support member 220-7.

FIG. 12 is a plan view of the upper elastic member 150 illustrated inFIG. 2.

Referring to FIG. 12, the upper elastic member 150 may include the firstto sixth upper elastic members 150-1 to 150-6, which are spaced apartfrom one another.

The outer frames 152 a and 152 b of the upper elastic members 150include first coupling portions 510, 560 and 570, which are coupled tothe housing 140, second coupling portions 520 a, 520 b, 570 a and 570 b,which are coupled to the support members 220-1 to 220-5 and 220-7, andconnection portions 530 a, 530 b, 580 a and 580 b, which connect thefirst coupling portions 510, 560 and 570 and the second couplingportions 520 a, 520 b, 570 a and 570 b to each other.

The support members 220-1 to 220-5 and 220-7 may be electricallyconnected to the second coupling portions 520 a, 520 b, 570 a and 570 busing, for example, solders or conductive adhesive (e.g. conductiveepoxy) 901 (see FIG. 14A). For example, one end of the respectivesupport members 220-1 to 220-5 and 220-7 may penetrate the secondcoupling portions 520 a, 520 b, 570 a and 570 b, and the solders 901 mayelectrically bond one end of the respective support members 220-1 to220-5 and 220-7 and the second coupling portions 520 a, 520 b, 570 a and570 b to each other.

For example, the outer frame 152 a of each of the first and third upperelastic members 150-1 and 150-3 may include the first coupling portion510, which is coupled to the first upper support bosses 143-1 to 143-4(see FIG. 5) of the housing 140, the second coupling portions 520 a and520 b, which are coupled to the support member 220-1 or 220-3, and theconnection portions 530 a and 530 b, which connect the first couplingportion 510 and the second coupling portions 520 a and 520 b to eachother.

For example, the outer frame 152 b of each of the second and fourthupper elastic members 150-2 and 150-4 may include the first couplingportion 560, which is coupled to the first upper support bosses 143 ofthe housing 140, the second coupling portion 570 a, which is coupled tothe support member 220-2 or 220-4, and the connection portion 580 a,which connects the first coupling portion 560 and the second couplingportion 570 a to each other.

For example, each of the fifth and sixth upper elastic members 150-5 and150-6 may include the first coupling portion 570, which is coupled tothe first upper support bosses 143 of the housing 140, the secondcoupling portion 570 b, which is coupled to the support member 220-5 or220-7, the connection portion 580 b, which connects the first couplingportion 570 and the second coupling portion 570 b to each other, and athird coupling portion 590, which is connected to the first couplingportion 570 and is coupled to the support member 220-6 or 220-8.

The support members 220-5 and 220-7 may be electrically connected to thesecond coupling portions 570 b using, for example, solders or conductiveadhesive (e.g. conductive epoxy).

Each of the first coupling portions 510, 560 and 570 of the outer frames152 a and 152 b of the upper elastic members 150 may include two or morecoupling regions S1 to S4, S5 and S6, or P1 and P2, which are coupled tothe housing 140. Although the coupling regions S1 to S4, S5 and S6, orP1 and P2 are configured as the through-holes 157, the embodiment is notlimited thereto. In another embodiment, the coupling regions S1 to S4,S5 and S6, or P1 and P2 may have any of various forms suitable for thecoupling of the housing 140, and for example, may be recesses.

For example, although the first coupling portion 510 of the outer frame152 a of each of the first and third upper elastic members 150-1 and150-3 may include four coupling regions S1 to S4 (see FIG. 14A), thefirst coupling portion 560 of the outer frame 152 b of each of thesecond and fourth upper elastic members 150-2 and 150-4 may include twocoupling regions S5 and S6 (see FIG. 15A), and the first couplingportion 570 of each of the fifth and sixth upper elastic members 150-5and 150-6 may include two coupling regions P1 and P2 (see FIG. 15A), theembodiment is not limited as to the number of the coupling regions.

The second coupling portions 520 a, 520 b, 570 a and 570 b of therespective upper elastic members 150-1 to 150-6 may be connected to anyone of the coupling regions S1 to S6 and P1 and P2 of the first couplingportions 510, 560 and 570 via the connection portions 530 a, 530 b, 580a and 580 b, and may be spaced apart from the remaining coupling regionsexcluding the aforementioned coupling region.

For example, one end of each of the connection portions 530 a, 530 b,580 a and 580 b of the upper elastic members 150-1 to 150-6 may connectany one of the coupling regions S1 to S6 and P1 and P2 of the firstcoupling portions 510, 560 and 570 and the second coupling portion 520a, 520 b, 570 a or 570 b to each other.

The connection portion 530 a, 530 b, 580 a or 580 b of the upper elasticmember 150 may be bent at least one time, and a width W2 of theconnection portion 530 a, 530 b, 580 a or 580 b may be smaller than awidth W1 of the first frame connection portion 153 of the upper elasticmember 150.

Because of the width W2 that is smaller than the width W1, theconnection portion 530 a, 530 b, 580 a or 580 b may easily move in thefirst direction, and consequently, may distribute stress applied to theupper elastic members 150 and stress applied to the support members 220.

Although the width W1 of the first frame connection portion 153 of theupper elastic member 150 is greater than the width of the second frameconnection portion 163-1 or 163-2 of the lower elastic member 160, theembodiment is not limited thereto.

In another embodiment, the width of the connection portion 530 a, 530 b,580 a or 580 b of the upper elastic member 150 may be smaller than thewidth of the second frame connection portion 163-1 or 163-2 of the lowerelastic member 160. In this case, the width of the connection portion530 a, 530 b, 580 a or 580 b of the upper elastic members 150 may begreater than the width of the first frame connection portion 153 of theupper elastic member 150, without being limited thereto.

In a further embodiment, when the width of the second frame connectionportion 163-1 or 163-2 of the lower elastic member 160 is greater thanthe width of the connection portion 530 a, 530 b, 580 a or 580 b of theupper elastic member 150, the width of the connection portion 530 a, 530b, 580 a or 580 b of the upper elastic member 150 may be equal to orsmaller than the width of the first frame connection portion 153 of theupper elastic member 150.

For example, the first outer frame 152 a of each of the upper elasticmembers 150-1 and 150-3 may have a left-right symmetric shape about areference line 501 or 503. In addition, for example, the remainingportion of each of the fifth and sixth upper elastic members 150-5 and150-6 excluding the third coupling portion 590 may be left-rightsymmetrical to the first outer frame 152 b of each of the second andfourth upper elastic members 150-2 and 150-4 about a reference line 502or 504, without being limited thereto.

The respective reference lines 501 to 504 may be a straight line thatpasses through the center point (101, see FIG. 12) and a correspondingone of the corners 144-1 to 144-4 (see FIG. 5) of the housing 140. Here,the center point 101 may be the center of the bobbin 110 or the centerof the housing 140.

For example, in order to maintain balance of the housing 140 so as toprevent the housing 140 from tilting to one side, the coupling regionsS1 to S4, S5 and S6, and P1 and P2 of the first coupling portions 510,560 and 570 of the upper elastic members 150 may be left-rightsymmetrical to one another about the respective reference lines 501 to504, without being limited thereto.

For example, the first frame connection portions 153 of the first tofourth upper elastic members 150-1 to 150-4 may be rotation (e.g. 90degrees rotation) symmetrical to one another about the center point 101(see FIG. 12).

The first coupling regions S2, S3, S6 and P1 may be closer to thereference lines 501 to 504 than the second coupling regions S1, S4, S5and P2. Here, among the coupling regions S1 to S6 and P1 and P2, thefirst coupling regions S2, S3, S6 and P1 may be connected to or adjacentto the connection portions 530 a, 530 b, 580 a and 580 b of the upperelastic members 150, and the second coupling regions S1, S4, S5 and P2may be spaced apart from the connection portions 530 a, 530 b, 580 a and580 b.

FIG. 13 is an enlarged view of the first outer frame 152 a illustratedin FIG. 12.

Referring to FIG. 13, each of the connection portions 530 a and 530 bmay include a first portion 531 a or 531 b, which extends in thedirection parallel to the reference line 501 or 503, and a secondportion 532 a or 532 b, which has one end connected to a distal end 13 aof the first portion 531 a or 531 b and the other end connected to thesecond coupling portion 520 a or 520 b, the second portion 532 a or 532b being bent at the distal end 13 a of the first portion 531 a or 531 b.The shape of the connection portions 580 a and 580 b may be the same asthe shape of the connection portions 530 a and 530 b. The first portions531 a and 531 b of the connection portions 530 a and 530 b may have aline shape, such as a straight line shape, or a curved line shape havingat least one bent portion.

For example, the first portions 531 a and 531 b of the connectionportions 530 a and 530 b, connected to the first coupling portion 510,may extend from the center of the bobbin 110 toward the corner of thehousing 140, and the second portions 532 a and 532 b of the connectionportions 530 a and 530 b may be bent from the first portions 531 a and531 b in the direction opposite to the reference line (e.g. 501).

An internal angle between the first portion 531 a or 531 b and thesecond portion 532 a or 532 b may be smaller than 90° but limitedthereto.

Because the second portions 532 a and 532 b of the connection portions530 a and 530 b are bent from the first portions 531 a and 531 b, thesecond portions 532 a and 532 b may distribute stress applied to theupper elastic member 150 and may prevent the breakage of the connectionportions 530 a and 530 b.

The distance d1 from the reference lines 501 to 504 to the secondcoupling portions 520 a, 520 b, 570 a and 570 b may be greater than thedistance d2 from the reference lines 501 to 504 to the first portions531 a and 531 b of the connection portions 530 a, 530 b, 580 a and 580 b(d1>d2). For example, d2 may be maximum distance from the referencelines 501 to 504 to the first portions 531 a and 531 b of the connectionportions 530 a, 530 b, 580 a and 580 b.

The first connection portion 530 a and the second connection portion 530b of each of the first and third upper elastic members 150-1 and 150-3may be left-right symmetrical to each other about the reference line 501or 503, without being limited thereto.

The connection portions 580 a of the second and fourth upper elasticmembers 150-2 and 150-4 and the connection portions 580 b of the fifthand sixth upper elastic members 150-5 and 150-6 may be left-rightsymmetrical to each other about the reference line 502 or 504, withoutbeing limited thereto.

The second coupling portions 520 a and 520 b of the first and thirdupper elastic members 150-1 and 150-3 may be spaced apart from theremaining coupling regions S1 and S4 excluding the coupling regions S2and S3 connected to or adjacent to the connection portions 530 a and 530b. The coupling regions S1 to S4 may be left-right symmetrical to oneanother about the reference line (e.g. 501).

The support members 220-1 a and 220-1 b may be spaced apart from thehousing 140. For example, the support members 220-1 a and 220-1 b maypass through the first through-holes 147 a and 147 b formed in thesecond side portion 142 of the housing 140.

For example, the first upper support bosses 143-1 to 143-4 of thehousing 140 may be coupled to the through-holes 157 of the firstcoupling portion 510, and the first upper support bosses 143-1 to 143-4and the through-holes 157 coupled thereto may form the coupling regionsS1 to S4.

The first coupling portion 510 may come into contact with the uppersurface of the housing 140 and may be supported by the upper surface ofthe housing 140, whereas the connection portion 530 a may not besupported by the upper surface of the housing 140, and the secondcoupling portion 520 a and 520 b may not come into contact with thehousing 140 and may be spaced apart from the housing 140. In addition,the empty space between the connection portion 530 a and the housing 140may be filled with a damper (not illustrated).

The support member 220-1 a may be connected to the second-first couplingportion 520 a, and the support member 220-1 b may be connected to thesecond-second coupling portion 520 b. Each of the support members 220-1a and 220-1 b may be electrically be connected to corresponding one ofthe second-first coupling portion 520 a and the second-second couplingportion 520 b.

For example, the first and second coupling regions S1 and S2 may belocated at the left side of the reference line (e.g. 501), and the thirdand fourth coupling regions S3 and S4 may be located at the right sideof the reference line (e.g. 501).

The distance between each of the second and third coupling regions S2and S3 and the reference line (e.g. 501) may be smaller than thedistance between each of the first and fourth coupling regions S1 and S4and the reference line (e.g. 501).

The first coupling portion 510 and the second-first coupling portion 520a may realize single contact owing to the first connection portion 530a, and the first coupling portion 510 and the second-second couplingportion 520 b may realize single contact owing to the second connectionportion 530 b.

Referring to FIGS. 12, 15A and 15B, the first coupling portion 560 ofeach of the second and fourth upper elastic members 150-2 and 150-4 mayinclude the coupling regions S5 and S6, which are coupled to the housing140, and the connection portion 580 a may be connected to any onecoupling region S6 among the coupling regions S5 and S6.

The second coupling portion 570 a of each of the second and fourth upperelastic members 150-2 and 150-4 may be spaced apart from the remainingcoupling region S5 excluding the coupling region S6 connected to theconnection portion 580 a. The coupling regions S5 and S6 may beleft-right symmetrical to the coupling regions P1 and P2 of the fifthand sixth upper elastic members 150-5 and 150-6 about the reference line(e.g. 502 or 504).

The first coupling portion 560 of each of the second and fourth upperelastic members 150-2 and 150-4 may come into contact with the uppersurface of the housing 140 and may be supported by the upper surface ofthe housing 140, whereas the connection portion 580 a may not besupported by the upper surface of the housing 140, and the secondcoupling portion 570 a may not come into contact with the housing 140and may be spaced apart from the housing 140. In addition, the emptyspace between the connection portion 580 a and the housing 140 may befilled with a damper (not illustrated).

The distance between the sixth coupling region S6 and the reference line(e.g. 502) may be smaller than the distance between the fifth couplingregion S5 and the reference line (e.g. 502).

The first coupling portion 560 and the second coupling portion 570 a mayrealize single contact owing to the connection portion 580 a.

Each of the fifth and sixth upper elastic members 150-5 and 150-6 mayinclude the first coupling portion 570, which has the coupling regionsP1 and P2 for the coupling of the housing 140, the second couplingportion 570 b, which is coupled to any one of the support members, theconnection portion 580 b, which connects the first coupling portion 570and the second coupling portion 570 b to each other, and the thirdcoupling portion 590, which is connected to the first coupling portion570 and is coupled to the other one of the support members.

The first coupling portion 570 may come into contact with the uppersurface of the housing 140 and may be supported by the upper surface ofthe housing 140, whereas the connection portion 580 b may not besupported by the upper surface of the housing 140, and the secondcoupling portion 570 b may not come into contact with the housing 140and may be spaced apart from the housing 140.

The empty space between the connection portion 580 b and the housing 140may be filled with a damper (not illustrated).

The first coupling portion 560 of any one upper elastic member 150-2 or150-4 among the first to fourth upper elastic members 150-1 to 150-4 andthe first coupling portion 570 of a corresponding one of the fifth andsixth upper elastic members 150-5 and 150-6 may be spaced apart fromeach other, and may be left-right symmetrical to each other about thereference line (e.g. 502 or 504).

The first distance between the reference line 502 or 504 and thecoupling region P1, which is connected to the connection portion 580 b,among the coupling regions P1 and P2 of each of the fifth and sixthupper elastic members 150-5 and 150-6 may be smaller than the seconddistance between the reference line 502 or 504 and the remainingcoupling region P2 excluding the coupling region P1 connected to theconnection portion 580 b.

In another embodiment, in the case where the electrical connectionbetween the fifth and sixth upper elastic members 150-5 and 150-6 andthe lower elastic member 160 is not necessary, the fifth and sixth upperelastic members 150-5 and 150-6 may be omitted. In addition, in the casewhere the fifth and sixth upper elastic members 150-5 and 150-6 areomitted, the second coupling portion 570 a of the second upper elasticmember 150-2 may be aligned with the reference line 504 so as to overlapthe reference line 504, and the second coupling portion 570 a of thefourth upper elastic member 150-4 may be aligned with the reference line502 so as to overlap the reference line 502. This serves to limit thetilting and rotation of an Optical Image Stabilization (OIS) movableunit during hand tremor compensation.

The first and third upper elastic members 150-1 and 150-3 may have thesame shape, and thus a description related to any one of both the upperelastic members 150-1 and 150-3 may be equally applied to the other one.

In addition, the second and fourth upper elastic members 150-2 and 150-4may have the same shape, and thus a description related to any one ofboth the upper elastic members 150-2 and 150-4 may be equally applied tothe other one.

In addition, the fifth and sixth upper elastic members 150-5 and 150-6may have the same shape, and thus a description related to any one ofboth the upper elastic members 150-5 and 150-6 may be equally applied tothe other one.

Although each of the upper and lower elastic members 150 and 160 of theembodiment is divided into two or more parts, in another embodiment,each of the upper and lower elastic members 150 and 160 may not bedivided.

The second coupling boss 117 of the bobbin 110 may be coupled and fixedto a through-hole 161 a formed in the second inner frame 161-1 or 161-2of the lower elastic member 160 by thermal bonding or using an adhesivesuch as, for example, epoxy. The second lower support boss 145 of thehousing 140 may be coupled and fixed to a through-hole 161 b formed inthe second outer frame 162-1 or 162-2 of the lower elastic member 160 bythermal bonding or using an adhesive such as, for example, epoxy.

Each of the upper elastic member 150 and the lower elastic member 160may take the form of a leaf spring, without being limited thereto, andmay take the form of a coil spring, for example.

In one example, the connection portions 530 a, 530 b, 580 a and 580 b ofthe upper elastic members 150 may be formed by support members, forexample, springs (e.g. leaf springs). In another example, each of theconnection portions 530 a, 530 b, 580 a and 580 b of the upper elasticmembers 150 may include a zigzag-shaped region, or at least one curvedregion or bent region.

In another embodiment, the role of electrical connection between theupper elastic members 150 and the role of electrical connection betweenthe lower elastic members 160 may be exchanged.

The support members 220-1 to 220-6 according to the embodiment arespaced apart from the housing 140, and are directly connected to thesecond coupling portions 520 a, 520 b, 570 a, and 570 b and theconnection portions 530 a, 530 b, 580 a and 580 b, rather than beingfixed to the housing 140.

Because the connection portions 530 a, 530 b, 580 a and 580 b are notsupported by the upper surface of the housing 140 and the secondcoupling portions 520 a, 520 b, 570 a, and 570 b are spaced apart fromthe housing 140, the second coupling portions 520 a, 520 b, 570 a, and570 b and the connection portions 530 a, 530 b, 580 a and 580 b mayeasily move in the first direction. The support members 220-1 to 220-6according to the embodiment are directly connected to the secondcoupling portions 520 a, 520 b, 570 a, and 570 b and the connectionportions 530 a, 530 b, 580 a and 580 b, which are easily movable in thefirst direction, and therefore are more easily movable in the firstdirection than general support members, which are fixed to the housing140. In this way, the support members 220-1 to 220-6 may improve theaccuracy of hand tremor compensation. In particular, the support members220-1 to 220-6 may distribute stress due to falling and shock, which mayrestrict the deformation of the support members 220-1 to 220-6 andprevent electrical disconnection.

In addition, because the width W2 of the connection portions 530 a, 530b, 580 a and 580 b is smaller than the width W1 of the frame connectionportion 143, ease in the movement of the support members 220-1 to 220-6in the first direction may be enhanced.

In addition, when the width of the second frame connection portions163-1 and 163-2 of the lower elastic members 160 is greater than thewidth of the connection portions 530 a, 530 b, 580 a and 580 b of theupper elastic members 150, the connection portions 530 a, 530 b, 580 aand 580 b may easily move in the optical axis, or in the firstdirection, which is parallel to the optical axis, thereby distributingstress applied to the upper elastic members 150 and/or stress applied tothe support members 220.

In addition, because the connection portions 530 a, 530 b, 580 a and 580b are bent at least one time, the overall length of the connectionportions 530 a, 530 b, 580 a and 580 b may be increased. In this way,the embodiment may distribute stress applied to the upper elasticmembers 150 and/or the support members 220, and may prevent theconnection portions 530 a, 530 b, 580 a and 580 b from being broken bystress, which is applied to the upper elastic members 150 and/or thesupport members 220 due to shock.

In addition, because the connection portions 530 a, 530 b, 580 a and 580b realize single contact between the second coupling portion 520 a, 520b, 570 a, or 570 b and the first coupling portion 510, 560, or 570, easein the movement of the connection portions 530 a, 530 b, 580 a and 580 bin the first direction may further be enhanced, and the stress, which isapplied to the upper elastic members 150 and/or the support members 220due to shock, may be more efficiently distributed.

In addition, because the stress, which is applied to the upper elasticmembers 150 and/or the support members 220 due to shocks is distributedby the connection portions 530 a, 530 b, 580 a and 580 b, with regard tofeedback control for hand tremor compensation, the frequency resonancecharacteristic of signals output from second position sensors 240 a and240 b may restrict the generation of a high resonant frequency.

In another embodiment, a lens moving apparatus may include the bobbin110 in which a lens is mounted, the housing 140, which accommodates thebobbin 110 therein, the magnet 130 and the second coil 230, whichelectromagnetically interact with each other so as to move the housing140, an upper spring 150, which is mounted to both the bobbin 110 andthe housing 140, a curvilinear shock-absorbing portion having one endconnected to a portion of the upper spring 150, and a support member 220(e.g. a suspension wire) connected to the other end of the dampingmember. The shock-absorbing portion may be bent at least one time. Inaddition, the lens moving apparatus according to the present embodimentmay further include at least one of the constituent elements 120, 160,170, 180, 240, 250, and 300 illustrated in FIG. 2.

Here, the shock-absorbing portion may include the connection portions530 a, 530 b, 580 a and 580 b and the second coupling portions 520 a,520 b, 570 a and 570 b. The descriptions of the connection portions 530a, 530 b, 580 a and 580 b and the second coupling portions 520 a, 520 b,570 a and 570 b may be applied to the shock-absorbing portion.

In addition, the upper spring 150 may include the first inner frame 151,the first outer frame having the first coupling portions 510, 560 and570, and the frame connection portion 153.

The shock-absorbing portion may be located near a first connectionregion (e.g. the solder 901 in FIG. 14A) of the upper spring 150 and thesupport member 220. In addition, the shock-absorbing portion may belocated between a second connection region (e.g. any one of the couplingregions S1 to S6 and P1 and P2) of the upper spring 150 and the housing140 and the first connection region (e.g. the solder 901 in FIG. 14A).

For example, two shock-absorbing portions 520 a, 530 a 520 b, and 530 bmay be formed on at least one corner of the upper spring 150. The upperspring 150 may be divided into a plurality of upper springs 150-1 to150-8 and a plurality of shock-absorbing portions may be provided suchthat the shock-absorbing portions may be connected to the respectiveupper springs. A plurality of support members 220 (e.g. a plurality ofsuspension wires) may be provided such that the respective supportmembers (e.g. the suspension wires) may be electrically connected to acorresponding one of the upper springs via the respectiveshock-absorbing portions.

Next, the base 210, the circuit board 250, and the second coil 230 willbe described.

The base 210 may have a bore corresponding to the bore of the bobbin 110and/or the bore of the housing 140, and may have a shape that coincideswith or corresponds to that of the cover member 300, for example, asquare shape.

Referring to FIG. 10, the base 210 may have a stepped portion 211, towhich an adhesive may be applied when the cover member 300 is fixed tothe base 210 using the adhesive. At this time, the stepped portion 211may guide the cover member 300 coupled to the upper side thereof, andmay come into contact with the end of the cover member 300.

The stepped portion 211 of the base 210 and the end of the cover member300 may be attached or fixed to each other using, for example, anadhesive.

The base 210 may be provided with a support portion 255 on one sidethereof facing a terminal 251 of the circuit board 250. The supportportion 255 may support a terminal surface 253 of the circuit board 250,on which the terminal 251 is formed.

A second recess 212 may be formed in a region of the base 210corresponding to each corner of the cover member 300. When the covermember 300 has a protrusion formed at each corner thereof, theprotrusion of the cover member 300 may be fitted into the second recess212 of the base 210.

In addition, second seating recesses 215-1 and 215-2 may be formed inthe upper surface of the base 210 so that the second position sensor 240may be disposed in each of the second seating recesses 215-1 and 215-2.

The support member 220 may be configured as an elastic support membersuch as, for example, a leaf spring, a coil spring, or a suspensionwire. In another embodiment, the support member 220 may be integrallyformed with the upper elastic member 150.

Meanwhile, the support members 220-1 to 220-8 may be disposed on thesecond side portions 142 of the housing 140. For example, one or moresupport members 220-1 to 220-8 may be disposed on each of the foursecond side portions 142. In another embodiment, the support members 220may be leaf springs disposed on the first side portions 141 of thehousing 140.

For example, the second coil 230 may be disposed above the circuit board250, and the second position sensor 240 may be disposed below thecircuit board 250.

The second position sensor 240 may sense displacement of an OIS movableunit in the direction perpendicular to the optical axis. Although thesecond position sensor 240 and the magnet 130 may be arranged on thesame axis, without being limited thereto.

Here, the OIS movable unit may include an AF movable unit andconstituent elements mounted to the housing 140. For example, the OISmovable unit may at least include the AF movable unit and the housing140, and in some embodiments, the OIS movable unit may further includethe magnets 130-1 to 130-4. For example, the AF movable unit may includethe bobbin 110 and constituent elements, which are mounted to the bobbin110 so as to move along with the bobbin 110. For example, the AF movableunit may at least include the bobbin 110 and a lens (not illustrated)mounted in the bobbin 110. In some embodiments, the AF movable unit mayfurther include at least one of the first coil 120 and the firstposition sensor 170.

For example, the support members 220-1 to 220-4,220-5 and 220-7 may be electrically connected to the circuit board 250via thermal bonding such as, for example, soldering.

The second coil 230 is located above the circuit board 250 so as to beopposite to the magnet 130 fixed to the housing 140.

Although four second coils 230 may be installed on four sides of thecircuit member 231, the embodiment is not limited thereto, and only twosecond coils may be installed respectively in the second direction andthe third direction, or four or more second coils may be installed.

The housing 140 may move in the second direction and/or the thirddirection, for example, in the X-axis and/or the Y-axis via interactionof the magnet 130 and the second coil 230 arranged to be opposite toeach other as described above, thereby performing hand tremorcompensation.

The second position sensor 240 may be a Hall sensor, and any othersensors may be used so long as they can sense the strength of a magneticfield. For example, the second position sensor 240 may take the form ofa driver including a Hall sensor, or may be configured as a positiondetection sensor alone such as, for example, a Hall sensor.

At least one terminal 251 may be installed on the terminal surface 253of the circuit board 250. The circuit board 250 may receive externalpower through a plurality of terminals 251 installed on the terminalsurface 253 and may supply the power to the first and second coils 120and 230 and the first and second position sensors 170 and 240, and mayoutwardly output signals received from the first and second positionsensors 170 and 240.
